Question

Which expression converts 100 inches per minute to feet per minute ?

Answer 1

To convert inches per minute to feet per minute, we can use dimensional analysis to help us cancel out the inches:

$\frac{100in}{1min}*\frac{1ft}{12in}$

Since we are going to cancel out units that are found on both the top and bottom of the fraction bars, we can cancel out units of inches, and thus we are left with feet per minute.

Answer 2

Answer:

The expression is $\frac{100inches}{1minute}*\frac{0.08333feet}{1inches}$

Step-by-step explanation:

1 inch is equal to $\frac{1}{12}$ feet, so:

$\frac{1}{12}ft=0.08333 ft$

So, if we have 100 inches per minute, to convert it to feet per minute, we have to use the expression:

$\frac{100inches}{1minute}*\frac{0.08333feet}{1inch}$ = 8.333$\frac{ft}{minute}$

You need to have attention to put the unit that you need that convert on the denominator to operate and obtain your result.
